One tequila, two tequilas, three…
But she didn’t mention her penchant for tequila!
As Holly and Phillip headed to the studio to record their interview with Alan, the show host got in touch to get their drinks orders in advance.
"Looking forward to seeing you later - i'm sorting you out a lovely drink from my globe ;)" Alan Tweeted.
"Can we have 100% Agave Tequilla?" Phillip replied. "... Because @hollwills says there's no hangover!”
It wasn’t long before Holly and Phillip had put the theory to the test in the green room – and the great #tequilaexperiment was born!
"This was the beginning..." Phillip tweeted.
"This was the end..." he added, as Holly had a giggle posing for the snap!
